Definitions

  • Conventional navigation systems include, for example, a search function that searches for a guide route from the current position to a destination and a route guidance function that indicates the host vehicle position and the guide route on a display.
  • the navigation system accesses road data (e.g.., node data, link data) corresponding to roads throughout Japan and map drawing data for displaying maps.
  • This road data and map drawing data (hereinafter, this data will simply be referred to as "map data") is conventionally stored in an optical disk that can be read by the navigation system or stored in a hard disk provided as part of the navigation system.
  • JP-A-2000-36097 proposes a system that transmits map data directly from a host station to a mobile navigation system via a communication line or wireless communication. In order to reduce the amount of data transferred from the parent station to the mobile station, the system may transmits the difference between the old map data and the new map data from host station.
  • Navigation systems with internal hard disks are advantageous in that, for example, they can be made to have a large capacity.
  • a convenient map data updating method is not yet in widespread use. That is, when updating map data stored in the hard disk, the user often must take the navigation system out of the vehicle in which it is mounted and send it to the manufacturer, which is extremely troublesome for the user.
  • the map data must be transmitted via wireless communication in order to update the data without removing the internal hard disk type navigation system.
  • the volume of map data that must be transmitted is large so it places a transmission load on the network and communication costs are substantial.
  • the navigation system of Japanese Patent Application Publication No. JP-A- 2000-36097 must perform time and resource intensive processing to create a new version of the map data based on the differential data and the old map data. Moreover, the navigation system must convert the differential data and the like to a data format that is usable in search processing. Accordingly, this places a load on the navigation system and requires a long time to update the map.
  • a relay device for example, a relay device, a server, a map data updating system, and a map data updating method which enables navigation system map data updating to be easily performed.
  • It is beneficial provide, for example, a relay device, a server, a map data updating system, and a map data updating method which enables the amount of data transferred when updating the map data to be reduced and the load on the navigation system to be decreased.
  • Systems, methods, and programs for updating map data create differential data in a server by comparing an old version of map data stored in the server with a new version of map data and transmit the differential data from the server to a relay device.
  • the systems, methods and programs create updated map data by combining the differential data received from the server with map data previously stored in the relay device.
  • the relay device may then be connected to an updated data storing device that disconnectably connects to both the relay device and the navigation system.
  • the systems, methods, and programs may then transfer the updated map data from the relay device to the updated data storing device and from the updated data storing device to the navigation system.

  • This map data may include, for example, road data corresponding to roads throughout Japan, drawing data for drawing roads and areas other than roads, and/or facility data.
  • the road data may include, for example, road type, road width, road name, intersection data, link data, and/or node data corresponding to the roads.
  • the drawing data may include, for example, various data for drawing roads, rivers, bridges, and/or other map features.
  • the facility data may include, for example, information relating to facilities and/or facility image data.
  • the map data may be in a data format that is different from the data format used, for example, by a navigation system 10 mounted in a vehicle C searching for a route
  • each road may consist of a plurality of componential units called links.
  • Each link may be separated and defined by, for example, an intersection, an intersection having more than three roads, a curve, and/or a point at which the road type changes.
  • node refers to a point connecting two links.
  • a node may be, for example, an intersection, an intersection having more than three roads, a curve, and/or a point at which the road type changes.

Therefore, it is possible to reduce the amount of data transmitted from the server 2 to the store terminal 4 in order to update the map data. Accordingly, data transfer can be completed in a short time.
  • the control portion 40 of the store terminal 4 may create the map data for updating 6a using the differential data received from the server 2 and the store side map data 46 stored in the store side map data storing portion 45.

  • the map data for updating 6a may be converted to the same data format as the navigation system side map data 16 provided in the navigation system 10. Therefore, the navigation system 10 only needs to read the map data for updating 6a stored in the updated data storing device 6 and replace the old version of the navigation system side map data 16 with it. Accordingly, the data format conversion processing is shared with the store terminal 4 so the load from computing and processing on the navigation system 10 can be reduced.
  • the server 2 may transmit license information for approving a data update to the store terminal 4. Also, the store terminal 4 may store received license information in the updated data storing device 6. Moreover, before reading the map data for updating 6a, the navigation system 10 may confirm the existence or absence of the license information and may perform data updating only if license information is stored. If there is no license information, the data updating is cancelled. Therefore, unauthorized writing and the like of map data for updating 6a can be prevented even when data for updating is sent and received between the server 2 and the navigation system 10.
  • the server 2 may receive different map data from a plurality of the distribution terminals 3 each having map data. Also, the server 2 may include server side map data storing portions 22 that store different map data. Accordingly, the server 2 is able to centrally manage different types of map data so differential data can be distributed to a greater number of store terminals 4.
  • the navigation system 10 may be made to be able to decrypt the license information.
  • the store terminal 4 may be made to be able to decrypt the license information.
  • the navigation system 10 may change the license information (step S4-3) after reading the map data for updating 6a.
  • the navigation system 10 may erase the map data for updating 6a stored in the updated data storing device 6.
  • the store terminal 4 may receive the differential data from the server 2, create the map data for updating 6a, and store that map data for updating 6a in the updated data storing device 6 every time the data in the navigation system 10 is to be updated.
  • the license information issuing process can be omitted.
  • the navigation system 10 may also perform conversion processing of the data format of the map data for updating 6a.
  • the server 2 may also perform the differential data distributing process when it has received a data request from the store terminal 4. Also, at the point when differential data is created, that differential data may be automatically transmitted to the store terminal 4.
  • the server 2 receives the map data from a plurality of distribution terminals 3. However, it may also receive it from only one distribution terminal 3. At this time, the distribution terminal 3 and the server 2 may also be integrated.
  • the updated data storing device 6 may be a storage medium other than a socalled external hard disk, such as, for example, an optical disk.
